Title: Circuit arrangement for telephone paystations for variously rated calls
IPC: B24B11/06
Filed: 1937-05-20
Abstract: 474,351. Automatic exchange systems. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES. May 20, 1937, No. 14102. Convention date, Dec. 24, 1936. Addition to 447,106. [Class 40 (iv)] The system described in the parent Specification in which the insertion of each coin sends an impulse of current of variable strength over one wire is modified by the provision at the substation of a relay R which in the case of an outgoing call energizes over the other wire and prevents the closure of the loop until the dial is moved off-normal. This arrangement enables the coin relays X10, X50 to be disconnected before impulsing begins. The movement of the switchlook operates first contact ka and then contacts ke, and the first movement of the dial operates contacts dk which remain until the switchhook is fully depressed. Upon removal of the receiver on an outgoing call, relay R(i) energizes and locks over the a wire in series with relay A, which connects up I, V and starts the line switch. On the first movement of the dial, the loop is closed at contact 1dk and A falls back and connects up D, which maintains I over the loop in series with B, and connects up Y. Relay I responds to dialled impulses. When the receiver is replaced, relay SM energizes over the b wire and locks in series with R(ii), which is of high resistance, so that I falls back and brings about release. Relay KR (not shown) applies battery to the a wire to operate the collecting magnet KM. Relays V, D, Y fall back in turn, releasing SM and R(ii). If the replacement is only a temporary one, R(i) holds over the a wire. If the switchhook is not fully depressed, I holds over contact 2dk, and the relapse of B applies busy tone. On an incoming call, cut-off relay U connects the a wire to earth in the final selector so that R is inoperative and the loop is closed at contact 2ke on the removal of the receiver.

Title: Improvements in Pencil Sharpeners.
Inventor: BEATTIE WILLIAM HERBERT TERRAN
IPC: B43L23/00
Filed: 1917-10-01
Abstract: 119,294. Beattie, W. H. T. Oct. 1, 1917. Pencil-sharpeners.-In a pencil-sharpener for forming chisel, conical, &c. points, means are provided for turning the pencil-holder about an axis passing through the tip of the point of the pencil so that the angle between the holder and the path of a reciprocating cutter is varied as the cutting proceeds, and preferably a ratchet device is provided whereby the angle may be reduced progressively by predetermined amounts; and means are provided for holding the pencil in a predetermined position against rotation on its axis and for effecting the longitudinal movement of the pencil necessary for the formation of a chisel point when the pencil is turned to present a different side to the cutter; alternatively, the pencil-holder may be fixed and the path of the cutter changed. The pencil-holder i is pivoted in brackets formed on the upper end of an inclined partition n and carries a rack l, which is operated to turn the holder by rotating a pinion m on a sleeve 9, Fig. 3, provided with a milled head 10; balls 15, Fig. 1, provided in holes L in the bearing for the sleeve 9 co-operate with two sets of holes in the sleeve so that the sleeve may be turned stepwise through half the distance between two holes. An index rod 17 resting on the holder i indicates the length of the cut. By operating a push-piece 13, Fig. 3, the pinion m may be disengaged from the rack l against the action of a spring 11 so that when one face of the point has been cut, the holder may be allowed to drop into the initial position shown in dotted lines, Fig. 2, for the formation of the next face. The cutter f is mounted on a plate v, which works in obliquelydisposed charnelled guides e, is provided with racks g parallel to the guides and is operated by mutilated pinions k on a hand-operated spindle j; springs h return the cutter when the teeth of the pinions k are clear of the racks A curved guard z secured to the cutter serves to deflect the cuttings into a tray d' in the lower part of the case. The pencil is held in a tube 6 which is provided with a split taper collar 7 and is inserted into the the holder i. To enable a chisel point to be formed, the tube 6 is provided with a cam groove I in which a detent finger 4 secured to the holder i engages, so that the tube and pencil are moved longitudinally when the tube is turned through 90 degrees by means of a milled head 8 for the formation of a fresh face of the point. In the modification shown in Fig. 8, the holder i is raised automatically as the cutting proceeds, the pinion m being rotated by a ratchet 20 operated through a lever 24 and a pawl arm 21 from a cam 26 on the spindle j. The mechanism is enclosed in a case a having a hinged lid a' provided with an observation window 2. A file, a knife and sandpaper may be contained in receptacles in the case or may be secured to the case. Marks on the top of the case indicate the distance the pencil must protrude from the tube 6.

Title: Change speed gear mechanism
Filed: 1921-05-24
Abstract: 178,353. Duran, L. May 24, 1921. Variable-speed gearing suitable for motor vehicles is controlled by a governor acting through a spring-controlled bar upon a cam-drum which changes the engagement of clutches. A driving-shaft 2, Fig. 1, carries fixed gears 9, 10, 11 meshing with gears 4, 5, 6 loose on a countershaft 1. A driven shaft 3 in line with the shaft 2 carries fixed gears 12, 13, the latter meshing with an idler 8<a>. The shaft 1 is driven at three speeds by using clutches 14, 15, 16, alternatively, and drives the shaft 3 forwardly or reversely according to the position of a pair of sliding gears 7, 8 adapted to mesh with the gears 12, 8<a>. The reverse is operated by hand. The governor 17 is driven through gearing 56, 58 from the gear 12 on the driven shaft. The governor sleeve 61 acts through bars 18, 19, Fig. 2, in such a way as to give a step-by-step movement to the cam drum 20. When the bar 18 is moved by the governor to the right against a spring 54, a spring 64 is compressed. When a certain tension is reached, a rod 65 acting on an arm 66 of the bar 19 moves the bar 19, and this through rack and pinion 78, 79 turns the drum 20. A locking bar 71, Figs. 3 and 4, is moved transversely by a cam groove 75 in the bar 18 and by spring-pressed bolts 72, 73, 76, 77 &c. upon the bar 19 effects the locking of that bar in proper gear positions. Cam grooves 40, 41, 42 on the drum are connected through ratchet clutches 26 with the gear clutches 14, 15, 16. A fourth groove 80 actuates a sliding member 81 which interconnects the throttle of the engine, an " accelerator pedal " for controlling the throttle, and a shaft 84<a>, which controls the clutches 26.

Filed: 1922-05-26
Abstract: 197,209. Reddie, L. N., (Officine Meccaniche Italiane). May 26, 1922. Frequency, measuring.- A movable indicator is acted on by two opposed electromechanical systems having, for a given frequency, equal impedances but different reactances so that any change of frequency upsets their equilibrium and causes automatic regulation of the total impedance of one or both systems. In the construction shown, one, system comprises a fixed coil f<1>, a moving coil m<1>, and an ohmic resisbance r connected in series across the mains, and the other system comprises a fixed coil f<2>, a movable coil m<2> and a variable inductance resistance l connected in series across the mains so that the torques exerted by the two systems on a pointer n oppose one another. For a certain value of the frequency the impedances of both systems are equal and the pointer n is dn equilibrium in the position shown. This equilibrium is upset on a change of frequency causing a contact c, carried by the pointer n, to vary the inductance l until the impedances of the two systems are again equal and a new position of equilibrium is established. The resistance r may be variable instead of, or in addition to, the inductance l. The position of the contact c may be varied by means of a relay. The moving coils m<1>, m<2> may be replaced by iron plates, and the fixed coils f<1>, f<2> may have iron cores. The movable system may in addition be acted on by an opposing force, for example that due to a spring.
